Mel Gibson is very concerned tht one of his children might be a target of kidnappers. He has trained them in a variety of skills that he feels are useful to prevent this from happening. All of them are expert drivers (even the ones that are underaged), all are proficient in both armed and unarmed combat, all of them can say "Help, police!" in the 30 most common world languages, and each one of them is an expert at tying and untying knots with their hands and their feet. Finally, each one of them has a GPS transmitter implanted subcutaneously for remote tracking. Gibson has also started to look into having their friends implanted (without their knowledge) so that he can keep an eye on those close to his children.
